Step 1:
a) Write the quadratic model
a = -15.64
b = -1.24
c = 5.23

b) t = 0.30

c) t = 0.52 seconds

d) 0.30 is more likely to be relaible.
e)
3/8 + 5/2
=3/8 + 20/8
= 23/8
or
= 2 7/8
The curves cross at coordinates (x, y) = (1, 4). The x-value is said to represent the increase in temperature, while the y-value is said to represent the numbers of visitors and those and who leave early.
The "solution" is the temperature change at which the number of visitors is equal to the number who leave early.
